Where to buy arrows?

My boss just gave me a bow he got from his nieghbor. It's a High Country Sniper with a 28-29" draw at 75-80lbs. I haven't shot a bow since I was a kid and had a 25lb recurve. So i'm wondering, where is a good place to buy arrows given that I'll only be shooting at makeshift targest behind the shop. Also, what kinds of targets/backstops do I need to use to not break arrows nor have them fly clean through?

You could go to Basspro shop and make sure you get the correct arrow length for you. I don't care what the bow says draw length is, you need to fit you and the arrow to the bow. I use a recurve to hunt with, which me the arrow and the bow go together. Maybe this will help.
